Hi, I have had a stock EVGA GTX 680 for nearly 8 months now, and only just noticed it was running in PCIe 2.0. However the first week I was using the card when it was first purchased, it would run PCIe 1.1 during idle and PCIe 3.0 during gaming (as it should)
Could it have been a driver update that could have changed this?
My system is:
Asus Rampage IV Formula ( PCIe 3.0 COMPLATIBE)
16GB of RAM
Windows 7 Ultimate 64-bit.
first of all i tell u that only single slot in the mobo will support pcie 3 and if u want to check these one u need gpuz in system idle the card will show u pcie 1.1 or 2.0
but under full load like gaming it show u 3.0 which means u r will configure ur gpu performance according to work u will not get anytime or 24 hrs show pcie 3.0 it only switch when gpu load increase neither could be upgraded + when sli the cards they only show 2.0 both cards just a single card can only switch to 3.0 pcie
just only u can do is update bios of mobo and latest driver that will increase game performance
